JP 05-077686 A

However, in such a conventional rice hull sorting apparatus, the supply amount at the feeding valve fluctuates due to differences in varieties, moisture content, degree of growth, etc., and the grains to be processed are stable on the swing sorting plate. There was a problem that the amount of grain could not be supplied and the working efficiency was lowered. In addition, when the oscillating sorting device stops, it is not possible to stop the flow of the grain toward the oscillating sorting plate through the feeding valve, and the grain is excessively supplied on the oscillating sorting plate, There was also a problem that the sorting accuracy was lowered. Furthermore, if a relatively large foreign object falls from the mixed rice tank and mixes with the grain, the feed valve will clog the foreign substance, hindering the supply of the grain to the oscillating sorting plate, and the sorting operation. There was a problem that workability deteriorated due to stoppage and frequent maintenance.
Accordingly, an object of the present invention is to provide a rice hull sorter with improved work efficiency, which enables smooth and stable quantitative supply of grains from a mixed rice tank to a rocking sorter.

  For this reason, the invention according to claim 1 stores a grain that has been wind-selected by the wind-selecting unit after being evacuated by the hulling unit, and also provides a mixed rice tank for supplying to the rocking-sorting unit. In the rice hull sorting apparatus provided above, a feeding roller interlocking with the swing sorting unit is provided at a lower portion of the mixed rice tank, and a regulating valve is provided above the feeding roller.

  According to a second aspect of the present invention, in the hull sorting apparatus according to the first aspect, the number of rotations of the feeding roller can be adjusted by an adjusting means.

  According to a third aspect of the present invention, in the hulling sorting apparatus according to the first aspect, the number of rotations of the feeding roller can be varied in accordance with the amount of grains on the swing sorting plate of the swing sorting unit. It is characterized by.

  According to a fourth aspect of the present invention, in the hulling sorting apparatus according to the first aspect, the restriction valve is swingable by an elastic body provided on the restriction valve.

  According to the first aspect of the present invention, the mixed rice tank for storing the grain that has been wind-selected by the wind-selecting unit after being evacuated by the hulling unit and for supplying the mixed rice tank to the swing-selecting unit is provided. In the rice hull sorting apparatus provided at the top, a feed roller interlocking with the swinging sorting portion is provided at the lower part of the mixed rice tank, and a restriction valve is provided above the feed roller, so that the grains in the mixed rice tank Regardless of the type of grain, the amount of moisture, and the processing status, the feeding roller can always supply a constant amount to the swing sorting unit. In addition, when a relatively large foreign object is clogged above the feeding roller, there is no need to stop supplying the grain to the swing sorting plate or to stop and disassemble the device to remove the foreign object. By opening the valve, foreign substances can be passed downward, and the grains can be reliably supplied from the mixed rice tank to the swinging sorting section. Therefore, it is possible to provide a rice hull sorting apparatus that improves the workability by increasing the grain sorting efficiency on the swing sorting plate.

  According to the second aspect of the present invention, since the rotation speed of the feeding roller can be adjusted by the adjusting means, the amount of the grain supplied from the mixed rice tank to the rocking and sorting portion can be dialed as necessary. It can be easily changed. Accordingly, it is possible to provide a hulling sorting apparatus that has improved sorting performance and workability that can be reliably sorted according to the state of the grain.

  According to the third aspect of the present invention, since the rotation speed of the feeding roller can be changed according to the amount of grains on the swing sorting plate of the swing sorting section, Accordingly, the supply amount of the grain from the mixed rice tank to the swing sorting plate can be automatically changed, and the grain can be reliably sorted by the swing sorting plate. Therefore, it is possible to provide a hulling sorting apparatus with improved sorting performance and workability.

  According to the fourth aspect of the present invention, since the restriction valve can be swung by the elastic body provided on the restriction valve, the foreign matter clogged above the feeding roller is allowed to pass through the restriction valve. After that, the regulating valve can be easily returned to the original position by the biasing force of the elastic body. Accordingly, it is possible to provide a rice hull sorting apparatus that reliably supplies a certain amount of grain from the mixed rice tank to the swinging sorting unit and improves sorting performance and workability.

In the lower part of the hull roll 11c, the hull discharge hull 14 in which the hull containing the small rice in the mixed rice (intermediate grain) falls from the wind selection path 12a, and further, the rear side of the hull discharge hull 14 is mixed rice. The rice bran and brown rice (selected grain) 15 are mixed in a row.

  The unillustrated spiral conveyance terminal side for conveying rice bran and brown rice that has fallen to the mixed rice receiver 15 is erected on the rear side of the side view machine body, and communicates with the mixed rice cerealing machine 3 having a plurality of buckets 3a. The mashing terminal side of the mixed rice cerealing machine 3 communicates with the mixed rice tank 4.

  Further, below the mixed rice tank 4, there is an equalizing trough 17 that conveys the mixed rice, and below this equalizing trough 17, a swing sorting unit 18 is provided. The swing sorting unit 18 has a distribution case 18a composed of a plurality of flow paths on the conveying end side of the balancer 17, a side of the distribution case 18a, and a swing sorting plate 18b composed of multiple stages. It is composed of a rice bran partition plate 18c, a brown rice partition plate 18d, and the like respectively disposed at the front and center of the sorting plate 18b.

  Below the swing sorting unit 18, a rice straw channel 19, a mixed rice channel 20, and a brown rice channel 21 are disposed in order from the front of the sorting unit 18. And the return mash inlet part 16a which has the terminal end of the flow path 19 for straws is provided with the several bucket 7a shown in FIG. The upper part of the reduced masher 7 is connected to the hopper 2. Further, a switching valve 22 is provided between the mixed rice flow path 20 and the brown rice flow path 21 to switch between brown rice in-machine circulation and out-machine discharge. And the brown rice flow path 21 is connected to the lower part at the rear end of the machine body, and the brown rice cerealing machine 6 having a plurality of buckets 6a is erected.

  Reference numeral 23 denotes an operation panel for operating the hulling sorting apparatus 1 and includes a controller (not shown) that drives and controls each part of the apparatus.

  Here, when carrying out the hulling operation using the hulling sorter 1, the hull (raw material grain) is supplied to the hull hopper 2, each part of the machine body is driven by a switch (not shown) of the operation panel 23, and the hull hopper 2 After opening a shutter plate (not shown) at the bottom and the rice cake supplied to the rice hull roll 11c is hulled, the mixed rice that has fallen is wind-selected by the wind selection path 12a, and the lightest rice hull is the suction fan 13 And is discharged to the outside through the rice husk discharge cylinder 5.

  In addition, the relatively light rice cake (including small rice) wind-selected in the wind selection path 12a is discharged from the rice cake outlet 14, flows into the rice cake reduction mill 7, and returns to the rice cake entrance 16a by the bucket 7a. It may be conveyed. On the other hand, the mixed rice of the heavy brown rice and the rice cake that has damaged the huller falls to the receiver 15, cerealed by the mixed rice cerealing machine 3 and supplied to the mixed rice tank 4, and then the equalized rice cake 17 And supplied to the swing sorting plate 18b via the distribution case 18a.

  The mixed rice is swayed by the swing sorting plate 18b, so that the brown rice having a small and heavy specific gravity is on the sway side, the rice with a larger specific gravity than the brown rice is on the swaying side, and the rice and brown rice not separated into the middle part. And mixed rice are sorted with drift distribution.

  Grains such as brown rice sorted by the swing sorting plate 18b are partitioned by the cocoon partition plate 18c and the brown rice partition plate 18d and discharged from the swing sorting plate 18b. At this time, when the distribution distribution of the grains on the rocking sorting plate 18b is unstable, the switching valve 22 causes the mixed rice flow path 20 and the brown rice flow path 21 to communicate with each other so that the mixed rice and brown rice flows. Is allowed to flow again into the catcher 15, but when the distribution of grain drift on the rocking sorting plate 18b is stabilized, the mixed rice flow path 20 and the brown rice flow path 21 are blocked. Can be switched.

  As a result, the mixed rice falls into the mixed rice channel 20 and is conveyed again to the sorting unit 18 through the receiving tray 15, and the brown rice is taken out from the brown rice channel 21 through the brown rice cerealing machine 23. It is. Further, the return rice cake (returned grain) is returned to the rice cake hopper 2 by the rice cake reduction mill 7 from the return rice cake outlet portion 16b through the return rice cake inlet portion 16a that has flowed in from the rice cake flow path 19, and is crushed again. The

  Next, the specific configuration of the feed roller of the mixed rice tank, which is a feature of the present invention, will be described. 5 is a left side view schematically showing the internal structure of the mixed rice tank, FIG. 6 is a left side view around the restriction valve schematically showing the operation of the restriction valve, and FIG. 7 is a swing sorting plate. FIG. 8 is a block diagram showing drive control of a motor that rotates a feeding roller, FIG. 9 is a left side schematic diagram of a regulating valve showing rotation by a rod, and FIG. 10 is a detection. FIG. 11 is a perspective view of an operation panel showing a dial and a sorting plate adjusting lever.

  As shown in FIG. 5, in the vicinity of the lower part of the mixed rice tank 4 and in the discharge port of the mixed rice tank 4, a feeding roller 30 having partition plates 32 provided at equal intervals from the central rotating shaft 31 is provided. It is installed so that it can rotate freely. In the figure, six partition plates 32 are provided at equal intervals, but the number of installed partition plates 32 is not limited.

  A motor 33 for rotating the feeding roller 30 is installed in the vicinity of the feeding roller 30 and below the mixed rice tank 4, and a driving shaft (not shown) of the motor 33 and a rotating shaft 31 of the feeding roller 30. A belt or the like (not shown) is wound between the two and the driving force of the motor 33 is transmitted to the feeding roller 30.

  The motor 33 includes a control unit 34 that adjusts the rotational speed of the drive shaft (not shown), and a dial 35 installed on the outer side of the motor 33 is connected to the control unit 34. The control unit 34, the dial 35, and the like constitute an adjusting means 36. Note that methods for controlling the rotational speed of the drive shaft in the control unit 34 include a resistance control method and a pulse control method. These methods are not limited, and are well-known techniques, and thus will be described in detail. Is omitted. Further, the adjusting means 36 is not limited to the dial 35.

  Further, a detector 37 such as a vibration sensor is installed at an appropriate position of the swing sorting plate 18b, and this detector 37 is linked to a motor 33 attached to the front plate 59 via a controller 38. The detector 37 such as a vibration sensor includes a capacitance type, an overcurrent method, a piezoelectric element type, and the like, and these methods are not limited, and are well-known techniques, so a detailed description will be given. Omitted.

  Furthermore, as shown in FIG. 7, on the swing sorting plate 18b, for example, in the middle in the left-right direction between the front inner wall 39 and the rear inner wall 40, the grains that are on the swing sorting plate 18b. For example, a detector 41 including a light emitting unit 41 a and a light receiving unit 41 b such as an ultrasonic sensor or an optical sensor is installed, and this detector 41 is linked to the motor 33 via the controller 38. In addition, the kind of detector 41 for detecting a grain, and the installation position of the light emission part 41a and the light-receiving part 41b are not limited above.

  Next, as shown in FIG. 5, the length between the front drop bar 42 and the rear drop bar 43 in the mixed rice tank 4 above the feeding roller 30 is increased in the left-right direction of the machine body. A metal regulating valve 44 is provided so as to be erected in the vertical direction and slidable in the front-rear direction. The restriction valve 44 has a rotating shaft 45 provided on the upper part of the restriction valve 44 attached to the lower end of the left side (front side in FIG. 5) of the rear drop rod 43.

  And the stay 60 which is the position which does not prevent the fall of a grain, Comprising: The lower end part of the right side part (back side in FIG. One end of an elastic body 46 such as a spring is attached to the vicinity of the lower end of the stay 60, and the other end of the elastic body 46 is provided at an appropriate position on the right side of the front drop bar 42. Attached to the stay 42a. Therefore, normally, the regulating valve 44 is held by the elastic body 46 at a vertical position at which the grain falling from the mixed rice tank 4 can be passed and fed to the feeding roller 30 at the lower end of the rear dropping trough 43, and relatively When a large foreign object is sandwiched between the front drop rod 42 and the rear drop rod 43 and comes into contact with the front surface of the restriction valve 44, the restriction valve 44 moves rearward about the rotation shaft 45 by its own weight. It is rotated.

  Reference numeral 52 denotes a stopper which is not limited to a material such as a metal or a resin, which restricts the forward swing of the restriction valve 44 attached to the inner side wall of the mixed rice tank 4.

  Further, in the mixed rice tank 4, a tank partition connected via a rod 54 to a shutter plate (not shown) that is provided above the rice huller 11 and adjusts the supply amount of the grain to the rice huller 11. A valve 55 is provided. The tank gate valve 55 senses the grain amount in the mixed rice tank 4 at a position where it swings according to the grain amount in the mixed rice tank 4 with the pivot shaft 55a as a fulcrum. The degree of opening and closing of the shutter plate is adjusted by sliding the rod 54 in conjunction with the swinging. For example, when the amount of grains in the mixed rice tank 4 is full, the shutter plate is closed and the hopper 2 Depending on the amount of grain in the mixed rice tank 4, such as stopping the supply of the grain to the sliding unit 11, the amount of rice bran in the rice bran unit 11 is controlled.

  Here, during the operation of the rice hull sorting apparatus 1, when the grains in the mixed rice tank 4 are dropped and supplied to the swing sorting plate 18 b to perform swing sorting, the feeding roller 30 is driven at a constant speed by driving the motor 33. Thus, for example, the grains falling from the mixed rice tank 4 are rotated between the front drop trough 42 and the rear drop trough 43, and the front drop trough 42 because the left-hand side counterclockwise direction is rotated. Then, it passes between the front plate 59 and flows into the frame of each partition plate 32 of the feeding roller 30 by a certain amount.

  For this reason, the grains included in the frame of each partition plate 32 are supplied into the equalizing mill 17 by the rotation of the feeding roller 30, and a fixed amount of grains is always oscillated and sorted through the equalizing bowl 17. Since it is supplied to 18b, there is no uneven supply of grain to the swing sorting plate 18b, and swing sorting with improved stability and sorting accuracy can be performed on the swing sorting plate 18b.

  However, when some sort of malfunction occurs in the swing sorting unit 18 and the operation of the swing sorting plate 18b is stopped, it is detected that the swing of the swing sorting plate 18b is stopped as shown in FIG. Based on the information detected by the device 37, the controller 38 stops driving the motor 33. As a result, the rotation of the feeding roller 30 is stopped, and the drop supply of the grains in the mixed rice tank 4 to the equalizing mill 17 is stopped. Therefore, the grains from the mixed rice tank 4 are unnecessarily placed on the swing sorting plate 18b. It is possible to prevent the grain from being clogged at the outlet of the mixed rice tank 4 and the reduction of the sorting accuracy when the swinging of the swinging sorting plate 18b is resumed.

  Further, when it is desired to increase, for example, the amount of grain supplied from the mixed rice tank 4 with the progress of the rocking sorting operation in the rocking sorting unit 18, the dial 35 provided near the motor 33 is increased. The rotation of the drive shaft (not shown) of the motor 33 increases according to the rotation amount of the dial 35 by the action of the control unit 34, and the rotation speed of the feeding roller 30 increases, The grain in the frame is supplied into the equalizing mill 17 at a speed higher than usual, and the sorting workability at the swing sorting plate 18b is improved.

  On the contrary, when the amount of grain supplied from the mixed rice tank 4 is to be decreased, for example, when the dial 35 is rotated in the decreasing direction, the operation of the control unit 34 causes the motor 33 to rotate. The rotational speed of the drive shaft is reduced according to the amount of rotation of the dial 35, and the grains in the frame of each partition plate 32 are less than usual in the dividing rice cake 17 due to the reduction in the rotational speed of the feeding roller 30. However, as a result of being supplied at a slow speed and reliably performing the sorting operation on the swing sorting plate 18b, the sorting accuracy can be improved.

  Furthermore, the grain supply amount from the mixed rice tank 4 can be increased or decreased according to the grain amount on the swing sorting plate 18b. In this case, as shown in FIG. 8, for example, it is detected that the layer thickness of the grain on the swing sorting plate 18b is thin (such as when the grain sorting operation is proceeding on the swing sorting plate 18b). Based on the information detected by the device 41, the controller 38 gives an instruction to increase the rotation speed of the motor 33 to the control unit 34, so that the rotation speed of the drive shaft in the motor 33 is increased by the action of the control unit 34. Then, as the rotational speed of the feed roller 30 increases, the grains in the frame of each partition plate 32 are supplied at a higher speed than usual into the sieving grinder 17, and the sorting workability on the swing sorting plate 18b. Is improved.

  On the other hand, for example, based on the information detected by the detector 41 that the layer thickness of the grains on the swing sorting plate 18b is thick (such as when the grain sorting work on the swing sorting plate 18b is delayed). Thus, the controller 38 instructs the controller 34 to reduce the rotational speed of the motor 33, whereby the rotational speed of the drive shaft of the motor 33 is reduced by the action of the controller 34, and the rotational speed of the feeding roller 30. As a result of the decrease, the grains in the frame of each partition plate 32 are supplied at a slower speed than usual into the equalizing trough 17, preventing excessive supply of the grains to the swing sorting plate 18 b and swinging. As a result of reliably performing the sorting operation on the sorting plate 18b, the sorting accuracy can be improved.

  Next, when the grains in the mixed rice tank 4 fall on the feeding roller 30, foreign matters such as relatively large pebbles are mixed in the mixed grains such as rice bran and brown rice. Is sandwiched between the front drop rod 42 and the rear drop rod 43, and when it comes into contact with the front surface of the restriction valve 44, the restriction valve 44 exerts a force on the weight of the foreign matter and the dropping direction. By receiving, the regulating valve 44 is rotated backward together with the stay 60 against the urging force of the elastic body 46 around the rotation shaft 45, so that the foreign matter is separated from the front drop rod 42 and the rear drop rod. Although not falling through 43, the size is larger than the grain, so that it does not fall into the feeding roller 30 and does not fall on the right side (the back side in FIG. 6) of the regulating valve 44. The left side of the leveling bar 17 shown in FIG. It is discharged from the foreign object removal unit 53 provided outside the apparatus.

  For this reason, the foreign matter is not sandwiched between the front dropping basket 42 and the rear falling basket 43, preventing the clogging of the grain due to the foreign substance, and preventing the grain supply to the leveling basket 17 from being stopped. Thus, the grains can be stably supplied to the swing sorting plate 18b. When the foreign matter or the like passes through and the force applied to the restriction valve 44 disappears, the restriction valve 44 turned rearward turns forward around the rotation shaft 45 together with the stay 60 by the urging force of the elastic body 46. And it is set as the structure which contacts the stopper 52 and returns to the original vertical position.

  Note that the rotation of the restriction valve 44 is not limited to the above-described self-weight of a foreign substance or the like. For example, as shown in FIG. 9, a stay connected to the same restriction valve 44 via a rotation shaft 45 as described above. One end of the rod 50 is attached to the rear portion of the 60 and the other end portion of the rod 50 is projected from the rear end portion of the mixed rice tank 4. Note that an elastic body 46 ′ is attached between the stay 60 and the stay 42 a as described above. Then, when the operator visually confirms that the grain supply amount to the swing sorting plate 18b has been reduced, the operator rotates the restriction valve 44 in the same manner as described above, for example, by pulling the rod 50 backward, and the foreign matter Then, the regulating valve 44 may be rotated about the rotation shaft 45 by the urging force of the elastic body 46 and returned to the original position.

  Further, the rotation of the regulating valve 44 can be automatically controlled by the detector 51. In this case, as shown in FIG. 10, for example, below the dropping trough 42 and on the left and right inner walls of the mixed rice tank 4, for example, a light emitting unit 51 a and a light receiving unit 51 b such as an ultrasonic sensor or a light sensor This detector 51 is linked to a motor 58 installed on the rear outer wall 57 of the mixed rice tank 4 for rotating the regulating valve 44 via the rod 56 via the controller 38. Is done. In addition, the kind and installation position of the detector 51 for detecting a grain are not limited to the above. Further, the stay 56 can be removed by directly attaching the rod 56 to the restriction valve 44.

  And it is inserted between the front drop trough 42 and the rear drop trough 43, foreign matter etc. contact the front surface of the regulating valve 44, and the grain from the mixed rice tank 4 does not fall on the feeding roller 30. On the basis of the information detected by the detector 51, the controller 38 drives the motor 58 to slide the rod 56 and rotate the regulating valve 44 as described above. The foreign matter is taken out from the foreign matter extraction portion 53 through the foreign matter extraction rod. When the detector 51 detects that the grain from the mixed rice tank 4 has fallen on the feeding roller 30, the controller 38 drives the motor 58, and the rod 56 slides to move the regulating valve 44 back to the original position. It is good also as a structure rotated and returned to a position.

  A dial for changing the rotation speed of the feeding roller 30 may be provided on the operation panel 23. In this case, for example, as shown in FIG. 11, a dial 35 ′ connected to the control unit 34 of the motor 33 is disposed on the rear inner surface of the operation panel 23. When the operator sees the state of the grain layer on the swing sorting plate 18b and needs to adjust the supply amount from the mixed rice tank 4, the dial 35 'is turned to the low speed side or the high speed side. By doing so, the rotational speed of the motor 33 is changed via the controller 34 as described above, and the rotational speed of the feeding roller 30 is controlled. Note that the sorting plate adjustment lever 61 provided on the rear surface of the same operation panel 23 and laterally arranged on the dial 35 'is a lever for adjusting the angle of the swing sorting plate 18b. When the operator sees the state of the grain layer on 18b and needs to adjust the grain layer to increase or decrease, the sorting plate adjusting lever 61 is turned to the large or small side to turn the sorting plate. The grain layer on the swing sorting plate 18b is adjusted by changing the angle of 18b.

  As described above in detail, the rice hull sorting apparatus 1 of this example stores the grain wind-selected by the wind sorting unit 12 after being removed by the hulling unit 11 and supplies it to the rocking sorting unit 18. The mixed rice tank 4 is provided above the leveling basin 17, and a feeding roller 30 that is linked to the swing sorting unit 18 is provided below the mixed rice tank 4, and a regulating valve 44 is provided above the feeding roller 30. Is. In addition, the rotation number of the feeding roller 30 can be adjusted by the control unit 34 and the dial 35 (adjusting means 36), and the rotation number of the feeding roller 30 is on the swing sorting plate 18b of the swing sorting unit 18. The regulation valve 44 can be swung by the elastic body 46 so as to be variable according to the grain amount.
